Wooden'Pipes'for Smoking To- .My invention relatesto 'the construction" of a pipe and the art of manufacture.

Pipes of wood such as bri er and imitation are often colored, she1lacked, 'varnijshedi oiled or' otherwise'treatedj in order to im;-' j

rove their appearance forj 't he purpose of display and sale The first smokerpf such; a ipe gets the 'flavor of' a'll' the finishing".- I materials on the interior ofgthe pipe together I with the efiects of combustion'of'the interior. surface layer of wood. The' flavor is sick, I ening. The factlis, that many smokers judging from their first experience with a? new pipe-believe that'they cannot smoke a pipe at all although from motives of economy and other attractive features of pipe smoking they would be very glad to adopt the use of a ipe.

It is my object therefore to so prepare an ordinary wooden pipe before selling the same for use that it will be equally attractive from the standpoint of appearance and will smoke sweet the first time it is tried.

The improved form of pipe has a bowl of suitable wood which is scorched on the interior sufliciently to remove any natural or artificial oils and resins and any coloring matter or other finishing material but without destroying the cellular structure of the outer part of the bowl or weakening it to any substantial extent. The method employed in the preparation of the bowl is the use of an open flame or heated iron or other member. Preferably the scorching is limited to the bottom and sides of the bowl leaving a narrow rim around the upper edge of the bowl unscorch'ed. This accomplishes all that is necessary in the elimination of ofi'ensive taste-producing elements and still preserves the outward appearance of the bowl.

A seal, cap or other suitable form of closure may be employed tocover the bowl and indicatethat it has been treated according to my invention and to prevent the entrance of foreign matter and the absorption of gasels by the prepared inner surface of the bow STERLING.

in the county of which the following is'a specifica-f a cap heated by {the interior'ofa'bowl.

In Fig. 3 the mandrel 5 is heated by a flame from a burner 6 and is of sufiicient size to scorch the interior of the bowl when tdhe1 pipe is relatively rotated on the man- In Fig. 4 the bowl is shown as being scorched on the interior by a flame from the torch 7. A ring 8 may be employed to prevent the scorching of the edge of the bowl.

In Fig. 5 the bowl is scorched by a cap a burner 10.

Any other suitable form of apparatus may be employed for carrying the invention into efl'ect.

By my invention the taste of freshly burning wood and varnish, dyes, oils or other finishing materials commonly used by pipe makers is removed and the pipe is thus made more readily salable or salable at a higher price because pleasanter to smoke. This process also enables me to make attractive and good-smoking pipes even of cheap material.

When a wooden pipe is first smoked the pores of the wood absorb the nicotin from shown as being 9 heated by aiflame from the tobaccoland" the smokin flavor of the I pipe is materially'change In a pipe treated according to my invention however, the, inner surface of the bowl is charred but remains absorptive and is free from nicotin as' well as fromother unpleasant taste'producing substances.

What I claim is v 1-.' As a new article of manufacture a new pipe bowl and stem formed of a single piece of natural wood and burned only On the inside'of the bowl by suitable means sub-- .the inner surface of the bowl absorbent and leaving the natural wood exposed and absorbent in the stem and without affecting the strength of the bowl or the stem and without adding nicotin.

of forming a wooden pipe 3. The art which consists in shaping the bowl and then burning the interior of the bowl sufficiently to remove unpleasant taste producing elements from the inner surface of the natural wood and without afiecting the strength of the bowl and without adding nicotin.

4:. The art of forming a wooden pipe which consists in first shaping the interior of the bowl, and then applying heat to the interior of the bowl and maintaining the heat substantially constant for a sufiicient length of time to burn the interior of the bowl sufiiciently to remove substantially all of the unpleasant taste producing elements from the lnner wall of the bowl, but with out materially affecting the strength of the bowl and without adding nicotin.

5. As a new article of manufacture, a new pipe bowl formed of natural wood with a charred inner wall formed by burning only the inside of the bowl by suitable means, the said bowl having substantially all the natural strength and absorptive properties of the wood, and the said inner wall being absorptive and free from nicotin and free from substantially all unpleasant taste producing elements.
